A thermal detecting device for sensing temperature at multiple locations proximate to the detecting device is provided. The detecting device has a pair of infrared detectors each configured to measure temperature of two locations by receiving infrared energy of the two locations. A housing encloses the pair of infrared detectors. The housing is configured with an aperture to allow the infrared energy of the two locations to be received by the pair of infrared detectors. A reflective mirror or two mirrors focus the infrared energy of the two locations towards the pair of infrared detectors. The detecting device may be configured to determine if there is a temperature differential at a location as the housing moves with respect to the location.

Apparatus and method for thermal detection

In an actively illuminated imaging system, illumination of a segmented scene is synchronized with an image sensing period. A scene is segmented into a plurality of scene portions utilizing a segmented lens. In an aspect, a first scene portion is illuminated when an imager is actively collecting photogenerated charge from the first scene portion, and a second scene portion is illuminated when an imager is actively collecting photogenerated charge from the second scene portion. The sensitivity of an image sensor is maximized, while simultaneously minimizing the amount of light that must be supplied to illuminate a scene. An irradiance pattern is varied allowing a more uniform distribution of light. Bands of varying wavelength, polarization, and light intensity may be variously applied to illuminate individual scene segments, as needed to enhance an identification of an object in the scene. The present invention is particularly useful with high frame rate imaging systems.

Synchronous imaging using segmented illumination

A detecting device for a vehicle and method thereof is provided. The device includes a first infrared detector, a second infared detector, and a controller. The first infrared detector is configured to repeatedly measure a temperature of a first target area by receiving infrared radiation of the first target area over a sampling period. The second infrared detector is configured to repeatedly measure a temperature of a second target area by receiving infrared radiation of the second target area over the sampling period. The controller is configured to receive and store the plurality of first and second signals, wherein the controller repeatedly compares a plurality of correlation values to a predetermined tolerance range above a minimum threshold value, wherein the correlation values are determined by repeatedly comparing a plurality of time delayed signals of the second plurality of signals to a real time signal of the plurality of first signals.

An illuminator assembly is provided for supplying night vision illumination. The assembly includes a support housing and an infrared illumination source. An infrared reflector receives the radiation emitted from the infrared illumination source and reflects the infrared radiation in a first substantially collimated field of view and transmits visible light therethrough. A visible light reflector is located behind the infrared reflective mirror for receiving visible light transmitted through the infrared reflector and reflecting scattering the visible light in a second field of view.

A fisheye-corrected lens system includes a plurality of axially aligned lenses. At least one of the lenses includes an aspheric surface and an image distortion of the lens system is less than about five percent at a maximum field angle. A furthest point of the aspheric surface is positioned within a distance less than about fifty percent of a diagonal dimension of an associated imager.
